Plinths constructed of plastic material

Abstract

A plinth constructed of plastics material including a platform; a continuous side wall depending from said platform and adapted to rest on the ground, said side wall including one or more peripheral portions and one or more divider portions, each of said one or more divider portions dividing the platform into at least two load bearing sections and each divider portion including two spaced apart divider wall portions joined by a bottom wall adapted to rest on the ground so as to support the adjacent load bearing sections of said platform, said platform, said divider wall portions and said bottom wall providing a continuous top face.

The invention claimed is: 
     
       1. A plinth constructed of plastics material including:
 a platform; 
 a continuous side wall depending from said platform and adapted to rest on the ground, said side wall including one or more peripheral portions and one or more divider portions, each of said one or more divider portions dividing the platform into at least two load bearing sections and each divider portion including two spaced apart divider wall portions joined by a bottom wall adapted to rest on the ground so as to support the adjacent load bearing sections of said platform, said platform, said divider wall portions and said bottom wall providing a continuous upper face. 
 
     
     
       2. A plinth according to  claim 1 , wherein each of said load bearing sections has at least one elongate support member depending from said platform and extending thereacross. 
     
     
       3. A plinth according to  claim 2 , wherein each elongate support member is connected to said peripheral wall portion at one end and to one of said divider wall portions at the other end. 
     
     
       4. A plinth according to  claim 3 , wherein each elongate support member is integral with said platform and said peripheral side wall and the divider wall portion to which it is connected. 
     
     
       5. A plinth according to  claim 4 , wherein said at least one elongate support member includes an array of elongate support members and the density of said array of elongate support members between said divider wall portions and said peripheral wall portion is greater than the density remote from said divider wall portions. 
     
     
       6. A plinth according to  claim 5 , wherein the bottom wall of said one or more divider portions has a substantially planar lower face. 
     
     
       7. A plinth according to  claim 6 , wherein the one or more peripheral portions of said side walls terminate in an outwardly extending continuous flange having an upper face and a lower face, the flange being contiguous with the bottom wall of said one or more divider portions and the lower face of the flange being co-planar with the lower face of the bottom wall of said one or more divider portions. 
     
     
       8. A plinth as claimed in  claim 7 , wherein said continuous side wall diverges away from said platform and said elongate support members depend from the platform for about half the height of said side wall so that like plinths are nestable for about half their height. 
     
     
       9. A plinth according to  claim 8 , wherein said one or more peripheral portions of said side wall include at least one pair of spaced apart opposed peripheral wall portions and wherein one of said divider portions extends from about the mid-point of one of said at least one pair of spaced apart opposed peripheral wall portions towards the other one. 
     
     
       10. A plinth according to  claim 9  including two divider portions extending towards each other from said at least one pair of spaced apart opposed peripheral wall portions towards each other. 
     
     
       11. A plinth according to  claim 1 , wherein said one or more peripheral portions of said side wall terminate in an outwardly extending continuous flange having a free edge remote from said platform and said platform has at least one peripheral corner and the side wall adjacent said at least one peripheral corner joins said flange adjacent its free edge. 
     
     
       12. A plinth constructed of plastic material including:
 a platform; 
 a continuous side wall depending from said platform, said side wall including one or more peripheral portions and one or more divider portions, each of said one or more divider portions dividing the platform into at least two load bearing sections and each divider portion including two spaced apart divider wall portions joined by a bottom wall so as to support the load bearing sections of said platform, said platform, said divider wall portions and said bottom wall forming a substantially continuous surface.
